I was involved in programming from the very beginning (the time of KIM-1) and I learned many programming languages, the major ones (C, C++, Java, Ada, Perl, Python, ...) and also very exotic ones (Assembler, APL, Fortran, Prolog, Lisp, ...). No language was more productive for me than Nim. Ever. It's the ideal "mix" of C, Python and Lisp with C++ native performance. Nim is really nice. I wonder why it is still barely known.

Note that meanwhile there is also NimScript, an interpreter for a subset of Nim, which can be used for shell scripts.

I have no problem with that because this way everyone can use his favorite notation. The only thing that strongly reject are strong spaces. That was a silly idea and should be removed instantly.
